Be it known that L' CARL at-Jeii'erson, in the county of Jefferson and State of- Wisconsin, Ah ave invented a new and-useful.Improvement in Samplers for Vacuum-Panszof which the Jfollowing is a completespec1ication.-

The main objects of-this invention are to provide an improved sampler' such as is used4 .for sampling milk; to provide a sampler adapted to' enable the operator to read his Atoi glve a better sample respecting the quan'- samples without leaving the operating'platform-.L and losing sightof his 'thermometer andgages; to provide a sampleradapted ftityof' milk obtained than has heretofore "rlings -beenpossibleg to provide a sampler adapted to register vat avhigher temperature than that obtained by the old method of sam-` and to providea cheap and simple device adaptedto be directly connected to A the vacuum pan and to be supplied by means of atmospheric pressure with the milk or other tiuid to be tested.

A :spec-inc embodiment. of the invention is illustrated in the accompanying drawings,

tion and isprovided near its topwith a therf' rod 8 is attached to the valve closure and.

' ;.Fi'gurel 1 isa fragmentary vside elevation ofY a vacuum pan with a sampler embodied section of the sampling and feeding-Bupa' In 'the construction. shown; thevacuum pan 1 isoff the-.usualfo'r ordinary construcmometer 2 adaptedtoshow the internal temperature of tliepan. Extending throughthe top ofthe pan, near one .side thereof,v and reaching into the lowerI portion of the'pan, i's-a pressure.. Pipe the milk; 'isia reservoir which is constructed in upper and lowerA section s which are joined together by a iunion `5. thereby permittingthe reservp'in to .be takentaparto'- L.

enable it and the pipe 3 tdbe'cleaned. tending downwardly and laterally from the lower end of the reservoir 4 is an intake pipe 6, having a valve or cock 7 at its end for the. admission of milk from the pan. For the purpose of operating said valve a A. BaUMnnLgf a 'citizen ot the United States, a'ud'resldlng neath 3. Onthe lower end of' 'the pipe 3, in position to be submerged in per portion extends upwardly. thioiigh-the tf-opioi the pan and is provided with a lever Q- at lits oit the pan at a point above thellevel of the milk and extends upwardly and is provided at its upper end .with aniair valve or cock -11 at a point abo\.e thefend ofA the pipe .3, and 'immediately below said cock lis a 'ameter than the pipe 3, extends'. from the upper end in-positlon to be grasped by the" operator. f An equahzing'pipe 10 leads Afrom the side lower portion of the reservoir 11 upwardly" throughthe -plpe 3 andthe coupling l13,' and turns laterally andisfconnectedin the.A top of the cylinder 16. The-pipe 15;,4 inter' `mediate lthe coupling '13 and the cylinder 16,1 is provided' withl a`valvef17 -adaptedto control back flow through said-pipe. The 16 is provided .at its top with a pet cock 18 adapted tofadmitfair'to thecylinder, and a sight. gage 19 is mounted 4on -the side of the cylinder to enable -thefopflv erator to Aread the level of the. fluid in thecup.

Extending downwardly i `the bot-tom of the. cylinder 164 is the 'drain pipe 20, which opens intorthe ,pipe10` ble# from the drain pipe 20 is the/sampler .pipe 21, vwhich-is provided with a samplercock 22, and mounted on its outerend is the samplercup 23. Theupper portion '2 4 ofthe sampler cup is of larger diameter ,than the flower 'portionfand its-bottom 25 is funnel shaped. A .test-cup 26j is carried 'in' 4the up- 24:01:' fthecup 2 3gand has' its. lower end extending into th'e smaller portion osaid cup', and is provided with a pe-' ripheraltlange 27 which seats on the bottom 25 and holds it in place. lhe top of the test-cup extends slightly above the top of the sampler cup to enable the operator to the cock 14;. Extending laterally.

' lhenV the milk' has raised suiiciently' the.

readimore. accurately the readings on the testing-instrument 28- Which may be inserted into-thfle'test-cup.

h e drainpipe 20 is provided .intermedihecylinder 16 and the'pipe l21 with a ...a A Controlling valve 29, and beneath the pipe21 Witha drain valve 30.-

"The operation of the construction shown is as follows: All-of the valves are'elosed,

and the panA is iilled with milk :to a. point above the reservoir` 4 and bgelofyv-the'opening of the pipe l10,-into the pan, there being aequalizes with that in the pan, and permits i' the milk to rise up'in reservoir 4 `and pipes 3 and 15 to the level o 'f the milk in the pan.

The valves 29 and 30, and 14 and 7 are'then closed and the air valve l1 `is'open ed' a1 1d` atmospheric pressure acting through pipes 12 and 3 force the milk down in the cup 4 and up through the pipe 15 into tlie cylinder-'16.

cylinder 16 to give' a proper quantityfora 'testpthe air cock ll'is closed, and-thejpet, cock 18, controlling valve 29 and sampler valve 22-are opened, thereby permitting the milk to runfrom the cylinder into thesam- A A pler 'cup and vtestlcup. When'theimilk rises tothe top of the ltest-cup the valve 22"is .closed andthev reading of the. instrumentj28 f a cylinder, atest-cup, means connecting sai' 'cylinder and said test-cupexterior to' the may be. taken. "Since the milkfis at the' level of thetest-cup and above the top ofthe samplercupghe reading may be accurately made.- .1A-iter invention` has lbeen herein shown and dei scribed, it will 'be'understood that many details 'of the invention 'shown may be varied y'so or omitted without departing from the scope 'of the claims.
